RAILWAY-TIE.

' Specication of Letters Patent.

Patented Apr.. 261, 1915.

Application filed- Dccember 20, 1912. Serial No. 737,780.

To all whom it may concern Be it known that I, BENJAMIN Q. P. Foss, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Railway-Ties, of which the following is a specification.

My invention relates to concrete railway ties in which a metallicstructure is embedded in a body of concrete.

The obj ect of my invention is to provide a tie of the characterdescribed, in which the tie plate is secured to the metal bar or barswhich reinforce the body of the tie, and

which will accommodate rails of various sizes and be safe and durable inuse.

Other objects and advantages of my improved tie will be renderedapparent in the following` specification when taken in connection withthe accompanying drawings, in

which- Figure l is a perspective view of one end of my improved tie witha portion broken away to show the interior construction.

Fig. 2 is a plan view of one of the ties, showing the rail in place onone end of the tie and the rail removed at the other. Fig. 3 is a sideelevation of the complete tie. Fig. 4 is a longitudinal section of oneend of the tie, taken on the line 4-4 of Fig. 2. Fig. 5 is a plan Viewof one end of the tie showing the tie plate placed at an angle for theswitch rails. Fig. 6 is a plan view showing a plate on the tie toreceive a sliding switch rail. Fig. 7 is a cross section showing amodification in which an old rail is used as the central bar; and Fig. 8is a detail showing a modification in which channel bars are used toinclose the body of the tie.

4o Referring more particularly to Figs. 1 and 4, it will be seen that Ihave provided-a tie body 10 made of a suitable concrete mixture, inwhich I have embedded a central longitudinal T-bar 13, and reinforcingbars 11 and 12 at either side thereof. These bars are preferably turnedinward at their ends, as shown at 11a and 12a in Fig. 2, thereby morefirmly anchoring them in the concrete body. To the central bar 13 Isecure a tie plateA 14 at each end, upon which the rails are placed andsecured by devices which I will describe later. l

The tie plates 14 are provided with downwardly projecting webs 15, whichterminate in horizontally disposed iianges 16 secured by rivets 17 tothe bar 13. To secure the' rails to these tie plates I provide clampingdevices 18 and 19, which are preferably composed of round bars bent intoa hook form, the bodies 20 of said bars being inserted in 60 guideapertures 20a in the bodies of said tie plates. These clamps aredisposed in opposlte directions, as clearly shown in Fig. 4, n order toengage opposite edges of the rail ase. 55

The clamping devices or hooks 19 and 2O are provided with threaded endsfor receiving adjusting and clamping nuts 21, by means of which the saidclamping devices may be made to engage rail bases of various sizes.These nuts are held in their adjusted positions by means of nut locks21a, which preferably consist of pieces of sheet metal, each having atongue 22, which may be bent over against the flat faces of the nut.

The tie plate is provided with slots 23 and 23a in its horizontal bodyportion to accommodate the clamping devices 18 and 19. The guideapertures are located in the vertical webs 15, and the bodies of theclamping devices 20 may bear along their upper surfaces against thelower face of the upper wall of the tie plate.

I provide recesses 24 and 25 in the body of the tie to permit access tothe nuts 21 and 85 also permit adjustment of the hooked ends of theclamping devices. After the clamping devices have been adjusted to theirfinal positions, I fill the recesses referred to with asphalt or othersuitable bituminous Ina- 9o terial or plastic substance, whichsubsequently solidifies. I use this asphalt, or like material, as acoating for all parts of the metal structure before it is embedded inthe concrete. By this means all rusting of the metal is prevented. Iprovide the upper surface of the tie plate with upwardly projecting lugs28, which receive the pressure of the rail, and between these lugs Iplace the asphalt. At the ends of the tie plate I provide the upwardlyprojecting ribs 26, and between said ribs I place a layer of pliable oryielding material 33 to serve as a cushion support-for the rail and toprevent the shocks `or blows of 'passing wheels from 105 seriouslyjarring the ties. This layer of material may alsol be used forinsulating purposes.

The asphalt or other protecting layer of bituminous material, or thelike, is shown at 11o 32 in various parts of the tie,*more particujlarly in Fig. 1. In Fig. 2 the asphalt is whichan old rail 29 is used asthe central bar. An old rail lwheninserted as shown serves veryefficiently for the purpose and the base flanges are very Vconvenientfor the attachment of the tie plates. rIhe rail head V29b provides greatstrength in this form.

l In Fig. 8 I have shown a modification in which I incjlose the concretebody of the tie in channel bars 30 and attach the tie plates 14@ to theanges thereof by rivets 17a. In this case the tie plate would have aposition above the body of the. tie.

In Figs. 5 and 6 I have shown modifications to accommodate switch rails.The tie plate may be placed in a diagonal position, as shown at'lllb inFig. 5 for fixed rails. A plate 35 may be placed on the tie in thedesired position to support sliding rails, as shown in Fig. 6.

VMy improved tie will be seen to be indestructible and capable ofserving its purpose forranindeiinite period. 'I'he metal parts, beingthoroughly protected by the coati-ng ofvasphalt, will not rust. Theadjustable clamping devices permit rails of differentV sizes to be usedwithout 1n any way injuring the ties when the change is made. It will beseen that the holding jaws produce a double vise grip on the rail base.Y Both the jaws are adjustable, thereby securing the rails firmly onopposite sides.

While I have shown andv described my invention with more or lessminuteriess and as being embodied in certain precise forms, yet -it willbe understood that I do not desire to limit myself thereto unduly, orany more than is pointed out in the claims. On

the contrary, I contemplate Y Y all proper changes in form,construction, and arrangement, the omission of immaterial parts, and thesubstitution of equivalents, as circumstances may suggest or necessityrender eX- vpedient.

What I claim. is Y 1. In a railway tie, a body of molded material, areinforcing barl of metal comprising a vertical web and an uppertransverse plate embedded in said body, a tieplate secured .i to saidreinforcing bar,and adjustable rail clampsY attached to said tie plateand movable longitudinally ofsaid tie.
